Specification of Letters Patent.

Patented Nov. 24, 1908.

Application led March 30, 1908. Serial No. 424,130.

To all whom t may concern.:

Be it known that I, OSCAR R. HUKLE, citizen of the United States, residing at Lexington, county of Fayette, and State of Kentucky, have invented certain new and useful Improvements in Carburcters and Mixers,

Of` which the followinglis a specification, reference being had therein to the accompanying drawing.

This invention relates to a carbureter and mixer, and particularly to a structure `adaptedfor application to an internal com- 4bustion engine.

provide a novel and improved construction of inlet' valve and means for controlling the same from a governor together with a con trolling disk mounted to coperate with said valve.

' Another object'of the invention is to provide a coperating mixer disposed relative to the discharge vfrom the valve and in con- ,"nection with means for automatically determining the proper proportions of air and hydrocarbon supplied to the engine.

@ther and further objects and advanta esv of the invention will be hereinafter fu ly set forth and the novel features defined by the appended claims. i l

In the drawingz-Figure 1 is a vertical section with parts in elevation; Fig. 2 is an enlarged detail'section of a portion of the valve and its seat taken at a right angle to Fig. 1; Fig. 3 is a vertical section of the valve seat; Fig. 4 is a horizontal section through the valve; Fig. 5'is a bottom plan of theregulator disk mounted Abeneath the valve seat; Fig. 6 is a similar view of the valve seat; Fig. 7 is a section through this seat on line 7-7 Fig. 3; Fig. 8 is an elevation of the discharge from the fuel feed tube,

' and Fig. 9 is a top plan of this part.

Like numerals refer to like parts `in the several views of the drawing.

The numeral 10 designates the valve cas-` ing which may be of any desired size or configuration and is provided at its upper portion with a mixing chamber 11 and at its llower portion with a fuel chamber 12, while intermediate of the mixer and fuel chamber an air chamber 13 1s provided and formed vwith an inlet 14 for air.

The lower end of the fuel chamber 12 is closed by a plate 15 secured to the casino' 10, and depending from this portion is a wetll or casing 16 provided at its lower portion with a liquid chamber 17 communicating with a supply pipe 18. lVithin the well 16 and extending into the fuel chamber 12 is a feed tube 19 having at its lower end acasing 20 provided with a check valve 21 and a cup or piston 22 which in the downward movement of thetube collects the liquid and forces it past the valve until sufficient quantity accumulates to overflow at the upper open end of the feed tube. This tube is supported and guided by a spider 23 mounted on the plate 15, while a s ring 24 extends from the upper portion o this spider to the distributer plate 25 over which the fuel flows. This plate is provided with a cap 26 s aced above the open end of the tube 19, as s own in Fig. S to prevent any upward spurt of the fuel toward the inlet of the valve. The feed tube 19 may be reciprocated by any desired means, but a preferable form thereof is herein shown where the tube is rovided with a stop or projection 27 adapte to bear against an arm 28 of the crank lever 29 which lever is mounted in a pivoting lug 30 carried on the plate 15. The upright arm of the crank lever is provided with a friction roller 31 bearing in contact with a cam face 32 disposed upon a disk 33 formed at the end of the sleeve or collar 34 which extends within the bearing casing 35 mounted at one side of the air chamber by means of the plate 36. The outer' endof this sleeve 34 is attached tothe extended hub 37 of the pulley 3S which is rotatably mounted upon thc bearing portion 35. The operating cam for the 4feed tube is thus actuated at a speed relative to the speed of the pulley and the feed consequently governed.

' The hub 37 is provided with arms 39 adapted to`support the governing weights 40 having the crank arms 41 mounted in the collar at 42 which is rotatable upon the valve rod 43 and held against longitudinal movement b v set nuts 44 at the opposite sides of the collar. This valve rod isconnected to a valve operating lever at 45 and extends into a tubular adjusting nut 46 having therein a spring 47 by which the tension necessary to "reciprocate the valve operating rod may be lating 59 monntedrelative to an indicator plate 60 upon the casing 10, as shown in Fig. 2. This disk is provided With a central opening 6*] through Whichthe valve stem 62 passes, and

the disk is supported in yielding contact with the under face of the valve casing by means of a tension spring 62 disposed between the disk'and crank arm 63 which embraces and -is pivotally connected with the valve shiftin rod at 45. The valve 64 is cylindrical an provided With air ports 65 in its side Walls and fuel portsv 66 in its bottom adapted to cooperate with the ports in the seat and disk.

The valve is also provided With a centrally extended hub 67 keyed to the stem 52 to rotate therewith and held against vertical displacement thereon by means of the nut 68 threaded upon the end of said stem.

' The mixing chamber 11 is provided -With the perforated plates 70 spaced from each other and disposed diagonally above the outlet `from the valve so that they effect a thor.- ough mixture of the air and fuel before it is carried from the connection 71 to the engine.

. These plates are supported by a lug 72 depending from the cap plate 73 mounted upon the casing to close the upper ortion. thereof and spaced apart by a bloc 74. The removal of this cap plate permits access to the valve and other parts Within the apparatus.

In the operation of the invention it will be seen that the governor pulley automatically feeds the fuel from the Well and discharges it over the distributer plate at the upper end of the feed tube from whence it is `brought by suction into the valve and commg in contact with the air from the chamber surrounding the valve thoroughly carburets the air and forms a mixture which is com# pleted in the passage through the perforated plates. Thesur lus of the fuel which is not vaporized and rawn into the valve flows back to the Well by gravityywhile the valve is controlled from the governor connection `relative to the load upon the engine so that the desired proportion of air and fuel may be at all times maintained. When it is necessary to vary this proportion it can be effected by a proper shi ting of the governing disk beneath the valve b which the relative amount of fuel entermg the valve may be controlled and indicated upon the outside of the casing. By means of this vdisk the This-lower wall is also provided with charge to be mixed can be controlled or entirely shut off.

bearings are equally vdistribut1-.d throughout their entire surfaces insuring absolute even wear at allpoints. The Weight of the valve resting upon its end compensates by its gravity for all Wear that is effected in use and consequently ts its seat leaving no space in which overflow can find lodgment to cause Well, a lever adapted to operate said tube, a
